Specification of Letters Patent. Patented Dec. 15, 1914;.

Application filed April 6, 1914. Serial No. 829,795.

To al l inhom-z't may concern i Be it known that I, ILLIAM KIRN, a

" citizen of the'United States, residing at New Gambria, in the countyof Saline and State of Kansas, haveinvented certain new and usefulImprovements in Gate and Barn-Door Latches, of which, the following is aspecification.

-\- My invention -1s a latch of rugged constfirngtion such as isrequired in a gate latch, or a banirdoor latch, or 111 other placeswhere it is subject to hard use, exposure,

' and abuse.

The object of my invention is to improve generally upon this type oflatches; to simphfy and at the same time strengthen the construction; toreduce the necessary number of parts; to avoid the use of separatespring, using the; handle as aspring; to make the latch readilyadjustable to any thicknessof door, gate, or other member to which it isto be applied, and to simplify the adjusting means; to make the latch sothat it can be used on ordinary swinging doors or gates, and also onsingle sliding doors, and on double sliding doors; to provide a simpleand eflicient" inside look for locking the latch against both openingand closing; and to provide the parts, improvements, and combinationshereinafter set forth;

Figure 1 is a horizontal section of an ordinary side-swing door andofth'e adjacentdoorjamb, with a plan view of a latch and keeper securedto those respective parts and made in accordance with the principles ofmy invention, the two face places being shown in section. Fig. 2 is afront or outside view of the same, without the door and jainb. Fig. 3 isa viewof the latch from the opposite side, or inside. Figs. 4 and 5 showthe face plates. Fig. 6 shows the stop and guide with a section of thelatch lever. on line 6 in Fig. 2. Fig. 7 is a face view of the keeper:and Fig. 8 is a sectional view of same on plane indicated by $3 in Fig.7. Fig. 0 shows the method of applying thesame parts to double slidingdoors. Fig. 10 shows the method-of applying the same latch to a singleslide door, with another form of keeper, the keeper being shown insection oi'l plane indicated by the line 10' in Fig. 12. Fig. 11 isanother View of the parts an in Fig. 10.

Fig. 12 1 Similar reference characters indicate similar parts throughoutthe several views.

13 represents a side-swing door, and it the adjacent jamb.

. 1 1 is the pin or pivot spindle extending through the door; the samebeing turned at substantially right angles and formed with a loop 15,and then returns substantially parallel in the same general rig'htangular direction, as indicated at 16, the entreme end being turned inclose to the spindle portion, as shown at 17.

18 is the outside face plate formed with the two holes 19 for thereception of the spindle portion 1a and the inturned end 17, the platebeing secured to the door by means of suitable screws 20. One side ofthe spindle is flattened, as shown at 21, and the spindle extendsthrough a correspondingly shaped hole in the central or hub portion ofthe latch lever comprising a handle portion 23 and'a locking arm 2-1,whose end is formed with the successively right-angular portions .25,213, and 27, as shown in the drawings. The central or hub portion QX-tends, as shown at '28, as a boss, into a hole 80 in the inside faceplate 29 secured in place by means of suitable screws 31. The latchlever is iirmly held to the spindle by means of a set-screw 32, whichprevents movement of the lever lengthwise 0f the spindle, thus holdingthe parts in proper relation.

33 is a guide and stop, to limit the oscillating movement of the latchlever.

It will be noted that the outside face plate is so fastened that the twoholes 19 are slightly oilset on opposite sides of the horizontal centerline of the handle; this being for the purpose of tending to force thehandle upwardly and the locking arm of the latch lever downwardlyagainst the guide. Also. the latch is operated by moving the handledownwardly and thus raising the locking arm, the downward movement, ofthe handle being against the tension of the resiliency of the parts 15and 16, which immediately restores the latch to normal position on beingreleased. Obviously, by shifting the face plate and the guide stop, thelatch may be made to work by lifting the handle, and may be applied leftside of the door and respond either to a downward or an upward movementof the handle. It will also .justed to any thickness ofv oor within the".plates" hold the spindle aways in proper pivotal' -po'sition.

- The keeper 3% is formed. with vertical: slots-35' through which thescrews 36 ezitendto' secure it'to the jamb, also witha tongue =3Zthat-is tapered, as shown at 39. and also bent inwardly at its-end 37;The tongue is also-formed with shoulders or notches 38.

41 is 'a rod mounted in slots 42 and having ends 40 turned at rightangles and em- -bra'cing the top and bottom sides of 'the keeper. F or aside-swing door, the keeper.-

By moving thehandle downwardly, the latch lever is released-and the door may beopened.

Having thus described any invention, 60

what I claim as new and desire to'secure by Letters Patent iszf r j vLlT-he combination of an, outside face plate having two holes adjacenttoeach "other, an inside face plate, a spindle extending through-oneyofthe holes in the outside face plate'and' also through said inside faceplate-, said spindle being formed-with an exteriorv right-angularlv bentportion to form an operating handle and returning to and engaging 1nsaid other hole, and a latch lever adjustably and non-rotatably securedto the spindle and pivoted in the inside face plate.
